1.8TSi oil consumption

[niggle]

Anyone else noticed unusually high oil consumption on the 1.8TSi?

I had to put 0.5L of oil in at around 470 miles as the dipstick was almost at the minimum mark.

i have done about 5300 all seems ok so far checked it the other day how many miles has the car done or is it 470 from new .if you have only done 470 then this is ok as when engine has bedded in it should be ok and mpg will get better

Are you sure it wasn't at that level when delivered? Mine has used next to nothing in 12 months.

470 miles from new.

I have my doubts about the "bedding in" aspect. Piston rings should bed in within the first 10 minutes of an engine's life or they will never bed in. As I understand it VAG run the engines through a break-in cycle before the car leaves the factory.

That's what I am hoping. Didn't check when we took delivery as you would expect that QA in the factory and PDI at the dealer would make sure that the oil fill was spot on.

i have worked for rover/BMW for 28 years and i can assure you that they are not fully run in at all ,that is why the running in period is usally 500 -1000 miles i always run a car in for 1500 the manual says 500 for the rings and the bore to become one

I have done 3,500 miles with no oil usage - the only thing that I have noticed is that you have to get the engine really hot before you check the level and let it stand for a good 5 minutes before checking. It was exactly the same on a Audi that I had - if you didn't get the engine really hot or checked level straight away you got a false reading. Checked this with the dealer and he confirmed it.

Thanks, Lawto48.

I have just read the Owner's Handbook. It states that the engine should be at normal operating temperature and then wait two minutes after stopping the engine before checking the oil level.

I checked mine stone cold, as I have always done for the past 30 years. I am less worried about the real oil consumption now but worried instead that I may have overfilled.

thats normal, both my mk2 1.8tsi and now my mk3 1.8tsi drank up to a litter of oil per 10,000kms.

Even on the manual it states thats normal.

1L every 10,000km would not bother me but my consumption works out at 1L every 1,500km. Not acceptable.

The worst case is the other way around. My Cupra when cold will read full. Drive it for 10 minutes leave it stand for 2 - 5 minutes and its 3/4 full.

My advice is to let it bed in then measure it every fill up. So for example my car will use 1/10 of a dipstick over 400 miles. If it reads unacceptable then take it back.

niggle I have got very similar mileage on my 1.8 TSI - about 600 miles now. I checked my oil yesterday on a warm engine after letting it stand a few minutes and it was full.

a few years back they recommended you left engine oil overnight then to check it in the morning when oil has drained into the sump as it makes no difference weather hot or cold still the same amount in there ,this is the way i still do it and a lot of other people do the same.it takes quite a while for the oil to drain out of the galleries back into sump

Like coolant, oil expands when hot. Cold oil is the worst case scenario for minimum fill.

When you have to put a litre in every 400 - 500 miles as I had to do on my 2.0 TFSI A4 then that's when you need to start worrying. My 1.4 TSI doesn't seem to have used anything in 8k miles but as others do I tend to check mine when its cold and all oil has drained back into the sump. I'll try checking it when the engine's warm to see if there's any difference.

ok niggle if you are right then when you check oil when its normal running temp and oil is hot if oil expands you would get a false reading in the stick.i tried this morning drove my car when i stopped the engine oil was hot left it 5 - 10 min and checked level ok ,have not used car since just checked it again cold hey prestoe level ok

Manufactures have different ways of checking oil. the best thing is follow the instructions in the handbook. I work on a 47 litre gas powered engine with a 900 litre oil sump it has 2 levels one for cold fill on an oil change and one for operating temperature so it does not have to be stopped to check/top up the oil.

 

[smurf123]

yes oil does expand but not enough that you would even notice.

yes oil does expand but not enough that you would even notice.

About 1% for every 14c change in temperature, so about 5% between hot and cold.

Could be significant in isolation but the engine will also expand/contract at the same time so it is difficult to say whether it would be measurable at the dip stick (which of course will also be longer when it's hot).

Really, it's not worth worrying about if the oil is at least half way between the marks.

As far as measuring consumption, it doesn't matter whether it's hot or cold so long as you measure it under the same conditions each time.

Also remember they are using smaller sumps than older cars now. I now try to follow the manufactures guidelines as they know best right? Especially when a warranty claims involved.
